No event/account not autorized?

I've been playing GW2 since the head start and haven't gotten any errors yet till now. I authorized my account when the game first came out but now I'm getting an error that says "There is no current GW2 event or this account is not authorized to participate in one". Is there any fix to this or do I just have to wait this one out? Sorry if there is already a thread about this, I didn't see one on the front.

(I preordered from gamestop too) Please forurm don't hurt me... I got this in the mail just now.
